Improvement in hay and cotton presses



diritti" NATHAN CHAPMAN, OF HOPEDALE, MASSACHUSETTS,

Letters Patent No. 110,011, dated December 13, 1870.

IMPROVEMENT IN HAY AND COTTON PRESSES.

The Schedule referred to in these Letters Patent and making part of the same. Y

To all whom it may concern:

Be it known that I, NATHAN CHAPMAN, of Hopedale, Worcester county, in the State of Massaehir' i eertainpeculiar combinations and arrangements for operating a hay and`cotton press, the same being fully set forth in the description and claims here following.

In the drawing herciubeforc mentionedm Figure 1 is a View in perspective of my improved press.

Figure 2, a top view. v

Figure 3, a-side elevation of the gripes and connected parts.

Figure 4, the same as scenlfrom the side toward the press-box.

The frame A supports the working parts of the press, and contains the box`B for receiving the material to be pressed or baled, the lower portion of the box being made removable, for the purpose of taking out the compressed bale.

The vertical bars G are secured to the bottom llieam D, and'supported at the top by the cross-piece Oneach of these bars are arranged- First, a guide, a.

Second, a gripe, b.

Third, a gripe, b'.

Fourth, a guide, a'.

Fifth, a jointed lever, c.

The gripe b is connected to the guide a by the link d pivoted in both; and the lever c is connected to the gripe li by the link d', which also holds the guide a'.

The guide a is connected to the beam F of the follower F by the pivoted link-d", and also to the jointed lever c by the links c e, and the link f. i

The pivot gg-forms the lirst or outer fulcrum of the jointed or compound lever c, and the pivot g', whichconnects it to the link d', forms 'the second or inner i'ulcrum. j As ol'tcn, therefore, as the arm c of the lever c is brought down in working the press, the guide a and the follower-beam F, together with it, are drawn down both by the links c c andthe link f.

lhergripe b', clutching the bar C, holds down the link d when the lever-handle is brought down, and the gripe li, in like manner, holds down the guide a, and prevents it from rising or springing back when the lever-handle c is raised to give the gripe b' a new hold upon the bar C.

rThe lever c is provided with several scores to receive the link f, so that the distance of the link from the fulcrum g may be varied as required.

On nu arm or projection of the gripe b are pivoted two props or braces, 7L and h', one of which, when turned down to. rest on the guide a', supports the outer end oi' the gripe b', and the other, being then turned up, supports the gripe b in like manner, and the gripes, with the parts connected tothein, then move freely on the bar C.

Then the guide aand the connected parts are fully raised, they may be supported by the hook i, vso that the follower F may be entirely disconnected from them by throwing baek the link d" from the follower- Tbeam F, thus leaving the follower free to be removed from the top of ythe box B.

If preferred, a hole may be made in the guide a and the bar C, so as to hold up the same parts by a pin inserted in these holes, or other equivalent device may be employed for the same purpose.

The standards G are secured upon the upper side beam of the frame A, and in them are pivoted the two levers H, projecting at one end over the 'follower F', and provided at their ends with the pulleys I and I.

Two other coresponding pulleys, I, are placed in the follower-beam F, o r otherwise connected to the follower.

The cords J are fastened to the inner ends of the levers H, and lthen passed under the pulleys I. and up over the pulleys 1' and I.

They may be operated by a crankwindlass, K, or by such other device as may be thought most eligible.

As' shown in fig. 1, the follower is taken olf of the top of the box B, and it is ready for filling. Cotton, hay, or'otlier material, as the oase may be, is then thrown in and trodden down, until there is enough in it to form a bale. The follower is then lowered upon it by releasing gradually the cords or ropes J, and the links d", having been thrown over upon the ends of the beam F, the guide (L is released from the hook 1', the props hand h' knocked out, so as to allow the gripes to clutch the bars U.

The levers care worked, and the contents of the box compressed by "the descent of the follower.

When the bale has been sufficiently compressed and scoured by bands, the lever-handle is to be raised, or partly raised, so that the gripe b will be released, and the strain ot' the pressure thrown upon the gripe b. The prop h is then to be set up between b and b', and the prop h between b and a@ The lever-handle heilig then brought down gently, both gripes will be released from the bar (l, and the follower, together with the gripes and connected part, may be raised to the top of the box vB by means of the ropes J.

When at the top the hooks are to be applied to the guides a, and, the follower being then lowered :t little way to release the links cl, they are to be'thrown back off the beam F, and the operation of' the ropes J may then be continued as before.

As soon as the follower meets the lever H, the ropes then operate the levers themselves, bringing them into the positionshown in g. 1, and the follower is thus taken out and moved to one side, so as to leave the top4 of the box open and free to receive material for another bale.

If preferred, the ropes J may be attached directly to the follower; but inthat case more power will be required to operate them.

That I claim, and desire to secure by Letters Patent, isl Y 1. The levers H, provided with pulleys I and I', when so arranged that the follower is raised, lifted out, and moved oli` from the top of the box by operating the ropes J, substantially as described,

2. The combination of the props It and h with the gripes b :rnd I1', substantially as and for the purposes specified.
